How clean is the water in Lake Erie?
Heidelberg University’s water quality lab showed that dissolved reactive phosphorous was steadily increasing since 1995. Water quality reports from the states bordering Lake Erie generally indicate improvement in Lake Erie’s tributaries. Strangely, there is no continuing water quality monitoring in Lake Erie itself.
Is Lake Erie water safe to drink?
Back in 2014, the City of Toledo, Ohio, issued a “do not drink” advisory when treated drinking water drawn from Lake Erie contained unsafe levels of a toxin called microcystin, produced by a bloom of harmful blue-green algae. Hypoxic water is usually acidic, discolored, and may contain iron and manganese.
How dirty is Lake Erie water?
The reason: The water was contaminated with algae-like cyanobacteria, which can produce toxins that sicken people and kill pets. This is the noxious goo that cut off about 500,000 Toledo-area residents from their tap water for three days in 2014 and made at least 110 people ill.
What is the prettiest of the Great Lakes?
Lake Huron, the second-largest of the Great Lakes, tops the list for its pristine turquoise waters, unparalleled shoreline sunrises, numerous lakeside parks, gorgeous beaches, and historic lighthouses. French explorers proclaimed it La Mer Douce, “the freshwater sea.” What’s more, Lake Huron is home to 30,000 islands!
Is the water quality in Lake Erie good?
The good news is that because Lake Erie is so shallow and turns over every 2.6 years, that it can get healthy pretty fast if the problem sources are reduced/eliminated. The Great Lakes Water Quality Agreement between the United States and Canada set phosphorus limits for Lake Erie at 0.1 mg/liter and mercury limits at .01 mg/liter.
How big is the hypoxic area in Lake Erie?
Since the early 2000s, the hypoxic (low-oxygen) area in the Central Basin of Lake Erie has increased to about 4,500 km2, on average, with the largest hypoxic event of 8,800 km occurring in 2012, subsequent to the record setting algal bloom in 2011. Hypoxic conditions can affect the growth and survival of fish species.
What was the phosphorus limit for Lake Erie?
The Great Lakes Water Quality Agreement between the United States and Canada set phosphorus limits for Lake Erie at 0.1 mg/liter and mercury limits at .01 mg/liter. At the time, all sources of nutrients, especially phosphorus, were targeted for reductions.
Why is excessive algal growth in Lake Erie a problem?
PURPOSE Excessive algal growth in Lake Erie poses significant threats to the ecosystem and human health – a source of drinking water for 12 million people in the U.S. and Canada.
